The Black Cat was Hollywood starlet Linda Turner, whose first adventure began when she suspected her director of being a Nazi spy. Trained as a stunt woman, she was an expert on Judo, motorcycle riding, lariat throwing, and other physical skills costumed crime fighters find handy; and her father, an amateur detective, had taught her the necessary mental skills. Knowing her superstitious quarry had a "thing" about black cats, she used that as a theme for her disguise. After smashing his spy ring, she combatted boredom with her glamorous but empty lifestyle by continuing to fight crime as The Black Cat.
